Powder coated aluminium sheet description
The surface shall be covered with fluorocarbon coatings with excellent weather resistance.
When polyvinylidene fluoride resin (PVDF) is used, the ratio of PVDF resin to resin raw material should not be less than 70%
The production process of powder coated aluminium sheet
Surface requirements for color-coated aluminum sheets: When viewing the coating surface vertically from a distance of 3 meters under natural light, the coating should be free of flow marks, cracks, bubbles, inclusions or other surface defects.

Aluminum sheet pre-roll coating process
Signi paint solid color, wooden grain, brushed, marble grain, chameleon etc thick sheet painting production line.
Multi-layer painting process
Multilayer spraying process with three sprayings (referred to as three sprays), spray bottom paint, topcoat and hood varnish and two sprayings (primer, topcoat).
Coating thickness: It can be divided into single coating (4μm-20 μm); double coating (25μm-28 μm); 3 coating (35μm-38μm).
At present, the current situation of Our country powder coated aluminium sheet is that the production capacity of ordinary products is excessive, and the production capacity of high-tech, high-precision and high-quality products is insufficient, which also leads to a large number of imports.
